Attachment Handling
Connect attachments that are suitable for the item that you want to measure
to the signal input terminals illustrated below. Select attachments from the
following list (see page 9 for attachment application examples).
• 5-cm pair lead
Can connect directly to a pin header or the item you want to measure. It
includes a damping resistor that takes pin header connection into account.
• 10-cm pair lead
Used in combination with a micro clip. It includes a damping resistor that
takes the micro clip into account. It is suitable for measuring relatively low-
frequency signals.
• Pin
The following four types are available. They are suitable for measuring
relatively high-frequency signals.
• Straight pin
• Angled pin
• Spring-type straight pin
• Spring-type angled pin
• A lead that you created using a kit
Create your own lead when you need a lead that is longer than the ones
included in the accessories, or when you want to prevent the lead from
coming loose from the probe head by using the retaining cover. For
instructions on how to create your own lead, see the next page.
Note
• The provided pair leads include the following damping resistors. These pair leads
can connect to a 0.64-mm square pin.
5-cm pair lead: 100 Ω, 1/4 W, 1%
10-cm pair lead: 150 Ω, 1/4 W, 1%
• For typical frequency characteristics of attachments, see appendix 1.

Because the probe input is high impedance, the inductance from the probe
head to the circuit under test has a large effect on the measured results of high
frequency signal components. When measuring signals that include frequency
components of 100 MHz or higher, we recommend that you use the shortest
attachments possible for both the positive and negative input terminals.
